Abstract
Illumination accounts for 22% of domestic energy consumption. Incandescent lighting is only 4% efficient in converting electricity to light; fluorescent lighting is better, but still only 25% energy-efficient. In contrast, light-emitting diodes (LEDs) developed at UCSB are approaching 80% efficiency. When scaled up and commercialized, this technology could realize $115 billion cumulative savings by 2025 in the United States alone, eliminating the need for 133 new power stations and saving 258 million metric tons of carbon emissions. Learn about the development of LED-based solid-state lighting technology, and how research at UCSB is at the forefront of these breakthroughs.
